    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D dose verification; uncertainties; low-density gel; fractionation dependence; characterization; normoxic gel; polymer gel dosimetry; MRI; Physics; Fysik;

    Abstract : Cancer is one of the main causes of death in the world, particularly in developing countries and is considered as a major public health problem. Radiation therapy has been an important modality for treatment of cancer for many decades. READ MORE

  2. 2. Radiotherapy Gel Dosimetry: Development and Application of Normoxic Polymer Gels

    University dissertation from Helen Gustavsson, Department of Medical Radiation Physics, Malmö University Hospital, SE-205 02 Malmö, Sweden

    Author : Helen Gustafsson; Lund University.; Lunds universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; tomografi; medicinsk instrumentering; Radiofarmaceutisk teknik; Radiopharmaceutical technology; proton; LET; FT Raman spectroscopy; MRI; normoxic gel; IMRT; 3D verification; polymer gel dosimetry; radiologi;

    Abstract : In many radiotherapy applications, true three-dimensional dosimetry with good spatial resolution that can be achieved in a single measurement would be of great value. Polymer gel dosimetry fulfils many of the demands on such a system. In this study, methods to facilitate the implementation of gel dosimetry have been investigated. READ MORE

  4. 4. Superabsorbent Polymers from the Cell Wall of Zygomycetes Fungi

    University dissertation from Chalmers University of Technology

    Author : Akram Zamani; Akram Zamani Forooshani; Högskolan i Borås.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; chitosan; cell wall; chitin; polyphosphates; dilute sulfuric acid; zygomycetes fungi;

    Abstract : The present thesis presents new renewable, antimicrobial and biodegradable superabsorbent polymers (SAPs), produced from the cell wall of zygomycetes fungi. The cell wall was characterized and chitosan, being one of the most important ingredients, was extracted, purified, and converted to SAP for use in disposable personal care products designed for absorption of different body fluids.

  5. 5. Generic Properties of Polymer Solutions

    University dissertation from Chalmers University of Technology

    Author : Takashi Uematsu; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Abstract : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. READ MORE
